a gas has a volume of 10 L at 0 degrees C. What is the final temperature of the gas in C if its volume increases to 27 L? Assume that amount of the gas and its pressure remain unchanged.
Predict the magnetic susceptibilities (para- or diamagnetic) and determine the number of unpaired electrons of each of the following complexes (consider C2O42- and H2O as strong field ligands which cause a large splitting of the d-orbitals).
Give the structure for an isomer of compound A that has a melting point that is appreciably different from that of A yet NMR spectra that are almost identical to those of A. Include wedge/dash bonds.
Meaning, use and calculation of empirical formulas, In this introduction are given the explanation of how to find out an empirical formula if one has found out the chemical elements of an unknown substance and measured their ratio of masses
Producing ethanol as a biofuel from sugars in corn (glucose) has become a major industry in the grain belt. This process can be summarized as follows, where glucose to form ethanol and carbon dioxide. Use bond energies to estimate Delta E for this..
What amount of the ultimate carbonaceous BOD is remaining after this time?
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment. Use enthalpy of formation data to calculate th..
Consider a gas mixture in a 1.50 dm3 flask at 22.0 C for each of the following mixtures, calculate the partial pressure of each gas, the total pressure and the composition of the mixture in mol percent
Would you expect a Diels-Alder reaction between maleic anhydride and naphthalene to require more or less harsh conditions
Which reaction intermediate is formed when 4-methylcyclohexene reacts with Br2 dissolved in CCl4?
What are the protons and neutrons that are emitted from a helium atom called? Atomic mass is expressed in atm.
A piston has an external pressure of 11.0 rm atm. How much work has been done if the cylinder goes from a volume of 0.130 liters to 0.460 liters.
To 1.00 L of a 0.100 M aquoeus solution of the weak base pyridine C5H5N is added 1.00 ml of 14.0 M NaOH. What fraction of the pyridine molecules in the resulting solution react with water to release hydroxide ions? (Kb C5H5N = 1.7 x 10^-9)
